Description

Technical Field

[0001] The utility model relates to the technical field of cable trench covers, in particular to a cable trench cover for a transformer substation. Background Art

[0002] The cable trench cover of a substation is a protective device used to cover the cable trench to protect the cables and the safety of maintenance personnel. It is usually made of wear-resistant, pressure-resistant, and corrosion-resistant materials such as steel plates, aluminum alloys, or plastics. By snapping together multiple covers, it can complete the protection of the cable trench.

[0003] The cover plates in the prior art can be snapped together and installed by two long protrusions on both sides. This connection method is relatively simple, but it cannot achieve a stable connection between the cover plates. If screws are used for connection, although the connection is relatively stable, it is more complicated to disassemble and replace, and it cannot achieve quick replacement of the cover plates, thereby increasing the workload of the staff. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a cable trench cover for a substation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cable trench cover for a substation includes a cover body 1. An upper edge 2 is provided on one side edge of the cover body 1, and a lower edge 4 is provided on the other side edge to match the upper edge 2. A limiting mechanism is provided on the upper edge 2, and a snap-fit ​​mechanism is provided on the lower edge 4. Two adjacent cover bodies 1 are snap-fitted together by the limiting mechanism and the snap-fit ​​mechanism.

[0007] The limiting mechanism includes two first circular holes 201 formed on the upper edge 2 of the cover body 1 , and the two first circular holes 201 are arranged near both ends;

[0008] The inner walls of the two first circular holes 201 are fixedly connected to a connecting disk 202 at the bottom, and a limiting rod 204 is slidably connected to the interior of the connecting disk 202. The top of the limiting rod 204 is fixedly connected to a fixed disk 203. A spring 206 is sleeved on the surface of the limiting rod 204, and the two ends of the spring 206 are respectively fixedly connected to the connecting disk 202 and the fixed disk 203; a connecting rod 207 is connected above the two fixed disks 203, and the two ends of the connecting rod 207 are respectively fixedly connected to the two fixed disks 203;

[0009] The clamping mechanism includes two second circular holes 209 opened on the lower edge 4 of the cover body 1. The positions of the two second circular holes 209 correspond to and match the limiting rod 204. The limiting rod 204 is slidably connected to the second circular holes 209.

[0010] Through the above technical solution, the stability of two adjacent cover bodies when placed in a substation can be improved, so that the two adjacent cover bodies will not be disconnected when the cover bodies do not need to be disassembled, thereby facilitating the stable connection and use between the cover bodies 1.

[0011] Furthermore, the bottom surface of the limiting rod 204 is an inclined surface.

[0012] Through the above technical solution, due to the design of the inclined surface, the limiting rod 204 does not need to slide upward when moving into the second circular hole 209, but can be driven to slide by the guidance of the inclined surface, which facilitates the use of the limiting rod.

[0013] Furthermore, an auxiliary groove 208 is formed on the upper surface of the cover body 1 on one side of the limiting mechanism, and the auxiliary groove 208 is located between the two first circular holes 201 .

[0014] Through the above technical solution, when the cover body 1 needs to be disassembled, the staff can pull up the connecting rod 207 from the position of the auxiliary groove 208. By pulling the connecting rod 207, the two limiting rods 204 can be driven out of the second circular hole 209, thereby completing the replacement and disassembly of the cover body 1.

[0015] Furthermore, the outer wall of the limiting rod 204 is provided with a plurality of protrusions 205, and the protrusions 205 are arranged below the connecting plate 202; the inner walls of the two second circular holes 209 are glued with rubber sleeves 210, and the surface of the rubber sleeve 210 is provided with a plurality of limiting holes 211, and the limiting holes 211 are snap-connected with the protrusions 205, and the number of the limiting holes 211 is not less than the number of the protrusions 205.

[0016] Through the above technical solution, the rubber sleeve 210 can increase the friction between the rubber sleeve 210 and the surface of the limiting rod 204. Furthermore, the protrusion 205 on the surface of the limiting rod 204 can be clamped inside the limiting hole 211. By setting the rubber sleeve 210 and the protrusion 205, the stability of the limiting rod 204 after being inserted into the second circular hole 209 can be greatly improved. When it is not subjected to a large pulling force by the staff, it will not be disconnected and can perform the limiting work well.

[0017] Furthermore, an auxiliary device 3 is provided at the center of the surface of the cover body 1, and the auxiliary device 3 includes a rectangular hole 37. The rectangular hole 37 is opened on the surface of the cover body 1, and a transparent plate 35 is fixedly connected to the surface of the rectangular hole 37. The surface of the cover body 1 is located on the peripheral side of the rectangular hole 37 and is slidably connected with a cover plate 31 adapted to the rectangular hole, and an anti-slip groove 32 is opened on the surface of the cover plate 31.

[0018] Through the above technical solution, when the cable needs to be inspected, it can be quickly observed through the transparent plate 35, so as to quickly find the location of the cable damage, which greatly increases the practicality of the cover body 1.

[0019] Furthermore, the side walls of the cover plate 31 are all arc surfaces 33. When the cover plate body 1 is used in daily life, the cover plate 31 will not affect the normal passage of workers or wheels.

[0020] Furthermore, a slot 34 is provided on one side of the rectangular hole 37 , and a block 36 matching the slot 34 is provided on one end of the cover plate 31 close to the slot 34 . The slot 34 and the block 36 enable the cover plate 31 to be engaged and connected with the cover plate body 1 .

[0021] Through the above technical solution, after the observation is completed, the staff can slide the cover plate 31 toward the slot 34, and further make the block 36 engage with the inside of the slot 34, so as to limit the cover plate 31 and make it less likely to slide during the covering work.

[0022] Compared with the existing technology, the cable trench cover of the utility model has the following beneficial effects:

[0023] (1) The cable trench cover of the present invention can improve the stability of two adjacent cover bodies when placed in a substation by providing a limiting mechanism and a clamping mechanism, so that the two cover bodies will not be disconnected when there is no need to disassemble the cover bodies, thereby facilitating the stable connection and use between the cover bodies.

[0024] (2) The cable trench cover of the present invention is provided with auxiliary devices, so that when the cable needs to be inspected, it can be quickly observed through the transparent plate, thereby quickly finding the location of the damaged cable, which greatly increases the practicality of the cover body.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The following embodiments are only used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] Example 1

[0034] like Figure 1 As shown, the utility model proposes a cable trench cover for a substation, comprising a cover body 1, an upper edge 2 being provided on one side edge of the cover body 1, and a lower edge 4 being adapted to the upper edge 2 being provided on the other side edge, a limiting mechanism being provided on the upper edge 2, and a snap-fitting mechanism being provided on the lower edge 4, and two adjacent cover bodies 1 being snap-connected by the limiting mechanism and the snap-fitting mechanism.

[0035] like Figure 2As shown, the limiting mechanism includes two first circular holes 201 opened on the upper edge 2 of the cover body 1, and the two first circular holes 201 are arranged near the two ends; the inner walls of the two first circular holes 201 are fixedly connected to the bottom position with a connecting disk 202, and a limiting rod 204 is slidably connected to the interior of the connecting disk 202, and the top of the limiting rod 204 is fixedly connected to the fixed disk 203, and the surface of the limiting rod 204 is provided with a spring 206, and the two ends of the spring 206 are respectively fixedly connected to the connecting disk 202 and the fixed disk 203; a connecting rod 207 is connected above the two fixed disks 203, and the two ends of the connecting rod 207 are respectively fixedly connected to the two fixed disks 203;

[0036] The bottom surface of the limiting rod 204 is an inclined surface. Due to the design of the inclined surface, the limiting rod 204 does not need to slide upward when moving to the inside of the second circular hole 209, and can be driven to slide by the guidance of the inclined surface, which is convenient for the use of the limiting rod.

[0037] The outer wall of the limiting rod 204 is provided with four protrusions 205, which are located below the connecting plate 202. A rubber sleeve 210 is glued to the inner wall of each of the two second circular holes 209. The surface of the rubber sleeve 210 is provided with four limiting holes 211 that match the protrusions, and the limiting holes 211 engage with the protrusions 205. The rubber sleeve 210 increases friction with the surface of the limiting rod 204. Furthermore, the protrusions 205 on the surface of the limiting rod 204 can engage within the limiting holes 211. The provision of the rubber sleeve 210 and the protrusions 205 greatly improves the stability of the limiting rod 204 after it is inserted into the second circular hole 209. The limiting rod 204 will not become disconnected unless subjected to significant pulling force by the operator, ensuring effective limiting operation.

[0038] like Figure 3 As shown, an auxiliary groove 208 is formed on the upper surface of the cover body 1 on one side of the limiting mechanism, and the auxiliary groove 208 is located between the two first circular holes 201. When the cover body 1 needs to be disassembled, the staff can pull up the connecting rod 207 from the auxiliary groove 208. By pulling the connecting rod 207, the two limiting rods 204 can be disengaged from the second circular holes 209, thereby completing the replacement and disassembly of the cover body 1.

[0039] like Figure 4As shown, the latching mechanism includes two second circular holes 209 formed on the lower edge 4 of the cover body 1. The positions of the two second circular holes 209 correspond to and match the limiting rods 204, and the limiting rods 204 are slidably connected to the second circular holes 209. This can improve the stability of two adjacent cover bodies when placed in the substation, ensuring that the two adjacent cover bodies will not become disconnected when the cover bodies do not need to be disassembled, thereby facilitating the stable connection and use of the cover bodies.

[0040] Example 2

[0041] like Figure 1 As shown, the utility model proposes a cable trench cover for a substation, comprising a cover body 1, an upper edge 2 being provided on one side edge of the cover body 1, and a lower edge 4 being adapted to the upper edge 2 being provided on the other side edge, a limiting mechanism being provided on the upper edge 2, and a snap-fitting mechanism being provided on the lower edge 4, and two adjacent cover bodies 1 being snap-connected by the limiting mechanism and the snap-fitting mechanism.

[0042] like Figure 2 As shown, the limiting mechanism includes two first circular holes 201 opened on the upper edge 2 of the cover body 1, and the two first circular holes 201 are arranged near the two ends; the inner walls of the two first circular holes 201 are fixedly connected to the bottom position with a connecting disk 202, and a limiting rod 204 is slidably connected to the interior of the connecting disk 202, and the top of the limiting rod 204 is fixedly connected to the fixed disk 203, and the surface of the limiting rod 204 is provided with a spring 206, and the two ends of the spring 206 are respectively fixedly connected to the connecting disk 202 and the fixed disk 203; a connecting rod 207 is connected above the two fixed disks 203, and the two ends of the connecting rod 207 are respectively fixedly connected to the two fixed disks 203;

[0043] The bottom surface of the limiting rod 204 is an inclined surface. Due to the design of the inclined surface, the limiting rod 204 does not need to slide upward when moving to the inside of the second circular hole 209, and can be driven to slide by the guidance of the inclined surface, which is convenient for the use of the limiting rod.

[0044] The outer wall of the limiting rod 204 is provided with two protrusions 205, which are located below the connecting plate 202. A rubber sleeve 210 is glued to the inner walls of the two second circular holes 209. The surface of the rubber sleeve 210 is provided with four limiting holes 211 that match the protrusions 205, and the limiting holes 211 engage with the protrusions 205. The rubber sleeve 210 increases friction with the surface of the limiting rod 204. Furthermore, the protrusions 205 on the surface of the limiting rod 204 can engage within the limiting holes 211. The provision of the rubber sleeve 210 and the protrusions 205 greatly improves the stability of the limiting rod 204 after it is inserted into the second circular hole 209. The limiting rod 204 will not become disconnected unless subjected to significant pulling force by the operator, ensuring effective limiting operation.

[0045] like Figure 3 As shown, an auxiliary groove 208 is formed on the upper surface of the cover body 1 on one side of the limiting mechanism, and the auxiliary groove 208 is located between the two first circular holes 201. When the cover body 1 needs to be disassembled, the staff can pull up the connecting rod 207 from the auxiliary groove 208. By pulling the connecting rod 207, the two limiting rods 204 can be disengaged from the second circular holes 209, thereby completing the replacement and disassembly of the cover body 1.

[0046] like Figure 4 As shown, the latching mechanism includes two second circular holes 209 formed on the lower edge 4 of the cover body 1. The positions of the two second circular holes 209 correspond to and match the limiting rods 204, and the limiting rods 204 are slidably connected to the second circular holes 209. This can improve the stability of two adjacent cover bodies when placed in the substation, ensuring that the two adjacent cover bodies will not become disconnected when the cover bodies do not need to be disassembled, thereby facilitating the stable connection and use of the cover bodies.

[0047] like Figure 5 As shown, an auxiliary device 3 is provided at the center of the surface of the cover body 1. The auxiliary device 3 includes a rectangular hole 37. The rectangular hole 37 is provided on the surface of the cover body 1. A transparent plate 35 is fixedly connected to the surface of the rectangular hole 37. A cover plate 31 that matches the rectangular hole is slidably connected to the surface of the cover body 1 around the rectangular hole 37. The surface of the cover plate 31 is provided with an anti-slip groove 32. When the cable needs to be inspected, it can be quickly observed through the transparent plate 35, thereby quickly locating the location of the cable damage, greatly increasing the practicality of the cover body 1.

[0048] The sidewalls of the cover plate 31 are all arc-shaped surfaces 33. When the cover plate body 1 is in daily use, the cover plate 31 will not affect the normal passage of staff or wheels. A slot 34 is provided on one side of the rectangular hole 37. A block 36 that matches the slot 34 is provided on the end of the cover plate 31 near the slot 34. The slot 34 and the block 36 connect the cover plate 31 to the cover plate body 1. After the observation is completed, the staff can slide the cover plate 31 toward the slot 34, further engaging the block 36 inside the slot 34, thereby limiting the position of the cover plate 31 and preventing it from sliding during the covering operation.

[0049] The operating principle of the cable trench cover of the present invention is as follows: when installing multiple cover plate bodies on the cable trench inside the substation, the cover plate bodies are placed on the surface of the cable trench, and then one cover plate body is slid toward the direction of the other cover plate body. When the two cover plate bodies slide together, the limit rod can be pressed by the inclined surface and then slide upward. When the limit rod moves to a position perpendicular to the second circular hole, the limit rod can be quickly inserted into the inside of the second circular hole under the action of the spring, thereby completing the stable connection between the two cover plate bodies; when the limit rod is not taken out, the two cover plate bodies are not easy to be disconnected, and a rubber sleeve is glued to the inner wall of the second circular hole, which can increase the friction between the rubber sleeve and the surface of the limit rod, and further the protrusion on the surface of the limit rod can be clamped into the inside of the limit hole. By arranging the rubber sleeve and the protrusion, the stability of the limit rod after being inserted into the second circular hole is improved, and the limiting work can be performed well. When the cover body needs to be disassembled, the staff can pull up the connecting rod from the position of the auxiliary groove. By pulling the connecting rod, the two limit rods can be driven out of the second circular hole, thereby completing the replacement and disassembly of the cover body.

[0050] There is an auxiliary device on the surface of the cover plate body. When it is necessary to detect whether the cable inside the cable trench is faulty, the cover plate can be pulled, and the card block can be further separated from the card slot. The cover plate can be pulled in one direction through the anti-slip groove on the surface of the cover plate. The staff can further observe the cables below well through the transparent plate inside the rectangular hole. After the observation is completed, the staff can slide the cover plate in the direction of the card slot so that the card block is connected to the card slot, and the cover plate can be limited to prevent the cover plate from sliding during the covering work.

Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. At the same time, the standard parts used in the present invention can be purchased on the market.
